TECHNICAL FIELD

The present invention relates to a pharmaceutical composition for treating or preventing epilepsy containing a sulfamate derivative compound and/or pharmaceutically acceptable salt thereof as an active ingredient. Furthermore, the present invention relates to a method for treatment or prevention epilepsy comprising administering a sulfamate derivative compound in a pharmaceutically effective amount to a subject in need of treatment or prevention of epilepsy.

BACKGROUND ART

CNS disorders nowadays concern large sections of the population. In particular on account of the increase in elderly people, the numbers of patients are increasing continuously.

Epilepsy is the most common neurological disorder, affecting about 1% of the population worldwide. Epilepsy describes a condition in which a person has recurrent seizures due to a chronic, underlying process. Epilepsy refers to a clinical phenomenon rather than a single disease entity, since there are many forms and causes of epilepsy. Using a definition of epilepsy as two or more unprovoked seizures, the incidence of epilepsy is estimated at 5 to 10 people per 1000. An essential step in the diagnosis and treatment of a patient with a seizure is to determine the type of seizure that has occurred. The main characteristic that distinguishes the different categories of seizure is whether the seizure activity is partial or generalized or unclassified.

For the general population there are approximately 20-70 new cases per 100,000 diagnosed each year with a 3-5% lifetime probability of developing the disease. The older established antiepileptic drugs (AEDs) phenytoin, carbamazepine, clonazepam, ethosuximide, valproic acid and barbiturates are widely prescribed but suffer from a range of side effects. Furthermore, there is a significant group of patients (20-30%) that are resistant to the currently available therapeutic agents. Since 1989 several new drugs have been launched, including felbamate, gabapentin, lamotrigine, oxcarbazepine, tiagabine, topiramate, vigabartrin, zonisamide and levetiracetam. While many of new AEDs show improved efficacies and side-effect profiles, about 30% of patients with epilepsy remain untreated. There is clearly a need for improved medication.

Biological Experimental Example. 1: Measurement of Anti-Epilepsy Activity (MES-Test)

In the MES test (Ref., G. Villetti et al. Neuropharmacology 40(2001) 866-878), an electrical stimulus (mice: 50 mA, 60 Hz, 0.2 sec, and rats: 150 mA, 60 Hz, 0.2 sec in the test animal) supplied by an 11 A Shocker (IITC Life Science Company) was delivered through corneal electrodes. All mice or rats assigned to any electroshock at peak time were treated with each test compound sample which was dissolved in 20% tween 80 prepared by saline solvent applied orally before the test. If the test animal's stretching of its hind limb in a straight line wasn't observed in the MES test, this results indicated that the test sample had anti-epilepsy activity. Three doses of the test sample were administered orally to 9-18 animals (3-6 mice per dose) for evaluating the respective doses at which 50% of the animals were protected from seizure (ED50). The ED50 value (median effective close) was calculated by Litchfield and Wicoxon log-probit method which is a dose-response relationship. The test results are shown in the following Table 4˜5. Experimental animals, male ICR mice and male SD rats, were purchased from OrientBio, Samtako, or Nara Biotech, Korea, and housed in cages (4-5 mice or 3 rats per cage) for 4-5 days. The range of mice body weight was between 19 and 25 grams and range of rats body weight was between 100 and 130 grams.

[Statistical Analysis]

The obtained results are shown as mean±sem. The difference between the groups was statistically analyzed by ANOVA, and then further examined by Dunnett's test or Bonferroni test. If p is less than 0.05, it was determined that the difference between the groups had statistical significance.

[Results]

Biological Experimental Example 2: Lithium-Pilocarpine Induced Epilepsy Test (LI-PILO Test)

Prevention Test

Male Sprague-Dawley rats (purchased from Orient Bio Inc. Korea) of body weight 175 grams were used for these studies and 3 rats per cage were housed for 4-5 days. On the day prior to SE, rats received 127 mg/kg lithium chloride (Sigma, St. Louis, Mo., U.S.A.) intraperitoneally (i.p.). Approximately 18-20 h following this treatment, rats were given an i.p. injection of 43 mg/kg pilocarpine (Sigma). An i.p. injection of 2 mg/kg methyl-scopolamine (Sigma) was administered 30 min prior to pilocarpine to block the effects of the muscarinic agonist on peripheral cholinergic receptors. Test drugs were dissolved in 20% tween80 (Sigma).

The drugs were administered intraperitoneally (i.p.) in a volume of 2 ul/g body weight. Pharmacological effects of all of the test materials were evaluated to compare test groups (n=6) with a control group (n=6). Control group was administered vehicle only. The efficacy was measured 0.5, 1, 2, or 4 hours after the administration of the test material. The time point that the most animals were protected was defined as peak time and the ED50 was determined at peak time. The animals were then transferred to observation cages and observed continuously for 90 min. Seizure was elicited in approximately 95% of the control group. Protection was defined as complete absence of seizure grade 3˜5 (Racine scale; Racine, 1972) over the 90-min observation period. The effective dose of the compound necessary to protect 50% of the animals against seizures compared to controls (i.e. ED50) was determined by a curve fitting program (Excel 2007, Microsoft).

Test drugs were dissolved in 20% tween80 (Sigma).

The drugs were administered intravenously (i.v.) in a volume of 2 ul/g body weight at SE onset. Pharmacological effects of all of the test materials were evaluated to compare test groups (n=3-6) with a control group (n=3-6). Control group was administered vehicle only. The animals were then transferred to observation cages and observed continuously for 90 min. Seizure was elicited in approximately 95% of the control group. Protection was defined as complete absence of seizure grade 3˜5 (Racine scale: Racine, 1972) over the 90-min observation period.
